-METHOD OF FORMI'NG WINDOW-GLASS CHANNELS.

Application led December 17, 192B. Serial No. 681,299.

The invention relates to the manufacture of channels and particularly metallic window-glass channels consisting of an outer channel-shaped strip and an inner V-shaped strip within the outer channel-shaped strip.

The main idea embodied in the invention is the forming of a window-glass channelby one continuous operation, decreasing the cost of manufacture. Another feature is the fashioning of a'pair of advancing fiat metallic strips or ribbons, and the nesting and securing of these strips to each other during their advancement. Further objects of the invention reside. in the knovel features as more fully hereinafter set forth.

In the drawings:

The strip 9'irst passes between the upper and lower cooperating rolls 11 and 12 of the first set of rolls 1, which form longiand at the same time return bend the edge portions 14. Then the strip passes between the upper and lower cooperating rolls 18 and 19 of the set of rolls 3, which bend the portions of the strip outside of the longitudinally extending beads 13 upwardly to a greater extent and at the same time bend the flanged ed esV 14 further downwardly. Alfter passing etween the rolls 18l `and 19, the strip 9 passes between the upper and lower cooperating rolls 2O and 2l of the set of rolls 4, which bend the portions of the strip outside of the beads 13 further upwardly.

The strip 10 first passes between the upper and lower cooperating rolls 22v and 23 of the first set of rolls 1, which form the strip with upwardly diverging port-ions.- The strip then passes between the upper and lower cooperating rolls 24 and 25 of the set of rolls 2, which operate upon the strip to form the downwardly extending portion 26 and the laterally and downwardly inclined portion 27 of the strip, the portion 26 forming the base of the completely fashioned strip, and the laterally and downwardly inclined portion 27 forming the yieldable-window-glass engaging portion ofthe strip. After passing between the rolls 24 and 25 the strip 10 passes between the upper and lower cooperating rolls 28 and 29 of the set of rolls 3, which bend the laterally and downwardly inclined port-ion 27 of the strip downwardly to -a greater extent. The strip then passes between the upper. and lower cooperating rolls 30 .and v31 of the set of rolls 4, which cut out portions of the laterally and downwardly inclined portion 27` of the strip, leaving open ended notches 32 longitudinally spaced along the strip. n y

Upon leaving the set of rolls'4, the strips 9-and 10 are converged, and the strip 10 is rotated through an angle of 90 Vand.

`nested within the strip 9 with its base 26 adjacent to and above the base 15 of the gaged in by the notched portion or yieldable window-glass portion 27 of the strip 10. During the advancement of the strips 9 and l0 along thev mandrel, their bases 15 and 26 respectively have struck upwardly therefrom the securing tongues and 36 by means of the shearing ioll 37 which forms a part of the set of rolls-5. Upon continued advancement of the strips, the struck up tongues 35 and 36 arebent back upon the bases of the strips by means of the shoulder 38 in rear of the set of rolls 5 and forming the rear end of the slot 39 which extends longitudinally at the bottom of the mandrel.

After having been bent back upon the bases of the strips the tongues are then crimped bycontactingwith the bottom of the mandrel at its rear end. This is secured by means ofthe roll40 mounted in the yoke 41 below the bases of the strips and held tightly there-against by means of the set screw 42 engaging the top of the yoke and abutting against the top of the mandrel 33.

Upon leaving the mandrel the strips pass successively through the sets of rolls 6 and 7, which comprise respectively lthe pair 'of cooperating upper and lower rolls 43 and 44 and the pair of cooperating upper and lower rolls 45 and 46, which operate upon bot-h the strips 9 and 10 to fashion the same to the desired final form. The pair of rolls 45 and 46 in particular do most of the fashioning of the strips, these rolls cooperating to bend the notched portion 27 of the strip 10 downwardly toward its base and to bend the portions of the strip 9 outside of the longitudinal beads 13 toward each other to complete the channel.

It is essential that the tongues 35 and 36, struck upwardly from the bases of the strips 9 and 10, respectively, be so located that the openings in the bases formed by striking up the tongues register with the notches 32 in the notched portion 27 ofthe strip 10, so that the means for securing the completed window-glass channel to the frame may be readily inserted through the notches 32 and extend through the openings in the bases. As shown, the striking up of the tongues is accomplished by the shearing projections or teeth 51 upon the shearing roll 37 equally spaced about its periphery, and the controlling of the operation of the shearing roll is accomplished by mechanism operated by the advancement of the strips.

As shown particularly in Fig. 7, the shearing roll '37 is frictionally driven, it being located between' the sections 52 and 53 forming the lower roll of the set of rolls 5, 54 being the upper roll of this set. 55 is a driving member formed of suitable material which is held against one side of the shearing roll 37 by means of the set screw 56 threaded in the section 53. The shearing roll 37 is held from rotation by the yoke 57 pivotally mounted upon the t-able 58 to which the mandrel 33 is secured. The yoke 57 has the depending projection 59 engageable with a shearing projection or tooth 5l and enibraces the mandrel 33 and is yieldably held so that its depending projection will be in the path of the shearing projection or tooth by means of the coil spring 60 connected to the upper end of the yoke and to the table 58. The yoke is actuated to release the shearing roll 37 by means ot' the release member 61 slidably engaging in a longitudinally eX- tending slot in the top of the mandrel and having a stem 62 slidably engaging in the block 63, with which the mandrel is preferably integral. The release member 61 has the depending projection 64 which is adapted to engage in the notches 32 in the portion 27 of the strip 10 by gravity, so that upon the advancement of the strips the release member will also be advanced. This advancement of the release member is continued until its rear end has engaged the yoke 57 to swing the same so that its depending projection 59 disengages from the shearing projection or tooth 51 of' the shearing roll 37. Then the depending projection 64 of the release member is disengaged from the notch in the strip 10 by means of the cam 65 upon the mandrel, which is engaged by thi inclined face 66 upon the release member. The parts are so located and the rate of rotation of the shearing roll and rate of advancement of the strip also isy such that when the shearing roll has been released one of its shearing projections or teeth will strike up the tongues in the bases of the strips so that the opening formed by striking up these tongues will register with a notch in the strip 10. After the release member has been disengaged from the strip 10 it is returned to its normal position by means of the yoke 57 through action of the coil spring 60, this yoke also being returned to its normal position where its depending projection 59 will engage a succeeding projection or tooth 51 of the shearing roll to hold the latter from rotation. When the release member has been returned to its normal position it will again be in position to drop by gravity into the succeeding notch 32 of the strip 10, after which the cycle of operations is repeated.

While I have used the term channel throughout the description, the invention in its broader aspects is not limited to a member having a strip of/true channel-shaped section but applies to shapes 'or moldings having nested' strips, neither of Which are necessarily of true channel-shaped section.

From the above description it Will be readily .seen that a completed channel strip, shape or molding comprising an outer member and an inner member is formed from a pair of iat metallic strips or ribbons during their advancement, which in the present instance is continuous.
